I can sum this item up in one word, WOW! It's a beautiful example of a rotary evaporator condenser. And I make no apology for seeing the beauty of this object. Sad? Maybe, but laboratory glassware has always been an interest of mine. I would wholeheartedly recommend this seller and their products. The condenser was wrapped up so well, it arrived in one piece and in the right direction as per indicated by the stickers on the box.
